In coal mining operations, the ventilation system is a key link to ensure the safety of miners and production efficiency. However, traditional air ducts often face the following problems:

 Heavy and difficult to handle: Metal or hard plastic air ducts are heavy, and their transportation and installation consume a lot of manpower, increasing operation costs.

 Prone to wear and cracking: The underground environment is complex, and ordinary air ducts are easily scratched by rocks and machinery, causing air leakage and a sudden drop in ventilation efficiency.

 Poor compressive resistance: It deforms after frequent folding or squeezing and cannot quickly return to its original shape, affecting the smooth flow of air.

 Insufficient corrosion resistance: Coal mines are damp and contain corrosive gases. Ordinary materials are prone to aging and have a short service life.

 The Flexible Lay-flat PVC coated air duct is specially designed to solve these problems. Through highly elastic PVC-coated fabric and scientific structural design, it provides a lightweight and high-strength ventilation solution.
